I have a 75g Fish Only tank with a 2' SnowFlake Eel, Purple Tang, Trigger, Small PuppyDog Puffer, and a Large Hermit Crab along with some urchins. I noticed that the fish were not eating well. After a couple days of observation, My tank had full blown Ick. Panic, I did. I pulled the fish and placed into a QT. But because I have skins and scales, I don't dare use copper, so I am trying hyposalinity at 1.009 and using baking soda to maintain PH. I am leaving my DT untouched for 1mth. Any ideas for this disaster. oh:
